Discussion (results) 1. Did changing the displacement of the mass affect the period of the mass and spring system? Justify your answer. As proven experimentally changing the vertical displacement or amplitude does not affect the period. As observed on all 3 trials with 3 different amplitudes, if we have the same mass for all 3 trials and we have a short amplitude it will oscillate slower than having a large amplitude in which the oscillation will be faster. Trial 3 had an amplitude of 30.0 cm and trial 2 had an amplitude of 60.0 cm, yet the average period for all 3 trials was around 1.93 or 19.1 seconds. Analysis
1. For each part of your experiment, list each variable involved and state whether it was held constant, increased, or decreased. The variables for part 1 were the masses and the spring constant; they stayed constant. The vertical displacement decreased as the spring constant increased. 2. In your experiment, what variables (physical properties) affected the period of a mass and spring system and how did they affect the period? 3.The data collected from the experiment
